q2 · i1 · causal · r1

One-way ANOVAs on CASUX subscale scores from 31 of 33 teachers in a between-subjects workshop study compared four conditions (Black, Voiceless, British, Indian). The article reports "no statistically significant differences across conditions for any subscale," with Proficiency F(3,27) = 0.232, p= .873, η2 =.025. Etiquette & Mannerism and Personality were likewise non-significant.

"Results indicated no statistically significant differences across conditions for any subscale. Proficiency showed no effect by condition,F(3,27) = 0.232,p= .873,η 2 =.025, confirmed by a Kruskal–Wallis test,H= 0.524,p=.914."

• Teachers drawing Black- and Indian-accented agents predominantly depicted them as human, while British-accented agents were drawn as technology — related
• A British-accented agent was framed as a background technological helper and othered rather than integrated as a peer — related
• An Indian-accented agent was integrated as a trustworthy conversational peer through repeated, contextually useful contributions — related
• Role ambiguity for a Black-accented agent destabilized trust, culminating in breakdown after the agent inaccurately tracked group decisions — related
